Description

Hardware & Electrical Specifications

‑ Model：IC695CHS012 ‑ Part Number：IC695CHS012 ‑ Module Type：RX3i 12‑Slot Universal Dual‑Bus Backplane ‑ Total slots：12 slots (Slot0: power‑supply dedicated; Slot1‑12: universal module slots) ‑ Backplane bus：Dual‑bus, PCI high‑speed bus + serial backplane bus ‑ Supported module types：  • IC695 series: CPU, power supply, I/O, communication modules  • IC694 series RX3i I/O modules  • IC693 Series‑90‑30 I/O & special‑function modules ‑ Backplane self‑consumption：  • 3.3VDC：600 mA  • 5VDC：240 mA ‑ Hot‑swap：Supported, must comply with GE official hot‑swap operation steps ‑ Installation：Horizontal mounting only; vertical installation forbidden ‑ Compatible power supply：IC695PSA040 / IC695PSA140 etc., power supply occupies slot0 ‑ PCB treatment：Conformal coated for dust‑moisture‑corrosion resistance ‑ Compatibility note：Cannot run standalone; must match RX3i dedicated power‑supply; vertical installation is not allowed; calculate total 5V/3.3V load consumption of all plug‑in modules; do not exceed power‑supply output budget。

Environmental Specifications

‑ Operating temperature：0 ℃ ~ +60 ℃ ‑ Storage temperature：‑40 ℃ ~ +85 ℃ ‑ Relative humidity：5%‑95% non‑condensing ‑ Installation location：Indoor cabinet, IP20 protection grade ‑ Cooling requirement：Reserve ≥102 mm (4 inch) clearance around backplane for natural air convection cooling ‑ EMC compliance：IEC 61000‑6‑2 ‑ Certifications：CE, UL Class I Div 2 hazardous‑location certification

Mechanical Data

‑ Weight：approx 2.3 kg ‑ Dimension：457.5 mm × 141.5 mm × 147.32 mm (L×W×D) ‑ Handling note：ESD‑sensitive backplane bus circuit; strictly horizontal installation; keep cooling clearance; do not bend backplane connector pins

Main Functions

1. Dual‑bus backplane carrier, provides power distribution and high‑speed internal communication channel for CPU, power‑supply and all I/O/special‑function modules.
2. Mixed‑mode compatible with RX3i native modules and legacy Series‑90‑30 I/O modules, realizing phased system upgrade.
3. Support module hot‑swap, replace I/O modules without system power‑off (follow operation manual).
4. No LED indicator on backplane itself; status indication is completed by power‑supply and each plug‑in module.

Installation & Wiring Requirements

1. Cut off whole rack power‑supply before installation / replacement. Hot‑swap only applies to I/O modules; cannot hot‑swap power‑supply and CPU. Strict anti‑static protection when handling backplane.
2. Fasten IC695CHS012 horizontally on cabinet DIN‑rail or mounting bracket, guarantee cooling clearance around the backplane. Install power‑supply module at slot0; insert CPU and each I/O module to corresponding slots and lock latches.
3. Power‑supply input wiring strictly follow GE RX3i hardware manual; reliable protective‑ground connection.
4. After replacement：power‑on rack; check power‑supply and each module OK indicator; download hardware configuration; complete full‑system online test.
5. Replacement note: Prohibit vertical mounting; calculate total backplane load power; strictly follow hot‑swap operating procedure; full‑system commissioning test mandatory before unit put‑into‑service。
